Description

Technical Field

[0001] This invention relates to the field of nylon fabric processing technology, and in particular to a device and method for co-processing nylon fabric printing and silver plating. Background Technology

[0002] Printing is used to print patterns, colors, or textures on the surface of fabric, serving both decorative and functional purposes; silver plating is used to deposit a silver layer on designated areas of the fabric, and is a key process that gives the fabric its core functionality. The processing quality and synergistic effect of the two processes directly determine the added value and performance of nylon fabrics.

[0003] In existing nylon fabric production processes, printing and silver plating operations are generally carried out in a discrete processing mode, that is, the two processes are completed by separate printing and silver plating equipment. The specific process is as follows: after the fabric is processed by the printing equipment, it is first rolled up and transferred to the storage area for temporary storage, and then transferred to the silver plating equipment for silver layer deposition. The two processes require multiple winding, handling, and reloading operations. This separate operation mode has low processing efficiency and the production capacity is difficult to match market demand. It not only increases labor costs, but also further increases the risk of fabric damage and contamination due to the uncertainty of manual operation, resulting in high overall production costs. In order to solve the above technical bottlenecks, this application proposes a nylon fabric printing and silver plating collaborative processing device, which integrates the printing and silver plating processes into one, fundamentally overcoming the many drawbacks of discrete processing. Summary of the Invention

[0006] Preferably, the coating slurry pushing cylinder has multiple circumferentially distributed cylinders, each of which is equipped with a liquid extraction pipe and a liquid outlet pipe. The end of the liquid extraction pipe away from the coating slurry pushing cylinder is connected to the bottom of the cylinder, and the end of the liquid outlet pipe away from the coating slurry pushing cylinder is connected to an annular pipe.

[0007] Furthermore, the top of the lamination printing drive rod is provided with an L-shaped connecting plate, the bottom of the L-shaped connecting plate is provided with an annular plate, the annular plate is slidably disposed on the outer wall of the limiting cylinder, the top outer wall of the annular plate is provided with multiple connecting rods, the top outer wall of the multiple connecting rods is provided with piston plates, and the multiple piston plates are respectively slidably disposed inside the multiple coating paste pushing cylinders.

[0008] Furthermore, a limiting plate is provided on the top outer wall of the limiting cylinder, and a limiting groove is provided on the limiting plate, and the L-shaped connecting plate is slidably disposed in the limiting groove.

[0009] Preferably, a push block is fixedly provided at the bottom of the lamination printing drive rod, a slider is slidably provided on the push block, the printing plate is provided at the bottom of the slider, a groove is provided on the push block, the slider is slidably provided in the groove, and a spring sheet is provided between the slider and the inner wall of the groove.

[0010] Furthermore, a groove is provided on the outer wall of the push block, a guide block is slidably disposed in the groove, a cover plate is connected to the guide block, the cover plate is slidably connected to the printing plate and the outer wall of the push block, and an elastic element is provided between the guide block and the inner wall of the groove.

[0011] Preferably, an mounting plate is fixedly provided on the outer wall of the support plate, the lamination positioning plate is fixedly connected to the mounting plate, a cylinder is provided on the top outer wall of the lamination positioning plate, and the cylinder is connected to the output end of the cylinder.

[0012] Furthermore, the top outer wall of the cylinder is provided with a plurality of circumferentially distributed guide rods, all of which are slidably connected to the lamination processing positioning plate, and the outer wall of the cylinder is provided with a feed pipe.

[0013] Preferably, a drying box is fixedly connected to the support plate, and a drying cylinder is provided inside the drying box. The nylon fabric passes through the drying box, and a horizontal plate is fixedly installed on the support plate, which is located below the printing plate.

[0014] A method for co-processing printing and silver plating on nylon fabrics comprises the following steps: Step 1: Connect the two ends of the nylon fabric to the external take-up roller and unwind roller respectively; Step 2: Inject silver paste material into the inner wall of the bottom of the cylinder; Step 3: First, control the cylinder to move downward on the lamination positioning plate so that the printing plate first contacts the nylon fabric, thereby realizing the printing operation; Step 4: The cylinder continues to move downwards, thereby driving the lamination printing drive rod to move and squeeze the coating paste to push the silver paste material into the cylinder; Step 5: Squeeze the material into the annular tube, where it is then sprayed out through the fan-shaped spray nozzles on the annular tube to achieve the silver plating effect.

[0015] Compared with the prior art, the present invention provides a device and method for the coordinated processing of printing and silver plating on nylon fabrics, which has the following beneficial effects: 1. This nylon fabric printing and silver plating co-processing device controls the downward movement of a cylinder, causing the printing plate to first contact the nylon fabric, thus achieving the printing operation. Then, as the cylinder continues to move, it drives the printing plate to move the lamination printing drive rod. When the lamination printing drive rod moves, it pushes the compressed coating paste into the cylinder, squeezing it into the annular tube, and then spraying it out through the fan-shaped spray head on the annular tube, thus achieving the silver plating effect. This application realizes the co-processing of printing and silver plating, improves work efficiency, meets market demand, reduces labor costs, and avoids damage or contamination of nylon fabric during manual operation.

[0016] 2. In this nylon fabric printing and silver plating co-processing device, the printing plate remains in contact with the nylon fabric during the silver plating operation. Therefore, it can prevent the fan-shaped spray head from spraying silver paste material onto the printing area, thus ensuring the printing effect. After the printing and silver plating operations are completed, the cylinder moves upward, causing the printing plate to separate from the nylon fabric. This allows for co-processing of printing and silver plating while ensuring that the two do not interfere with each other, thereby improving the use value. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Example 1: Refer to Figures 1-10A nylon fabric printing and silver plating collaborative processing device includes a support plate 1 and a lamination processing positioning plate 201 fixedly mounted on the support plate 1. A cylinder 3 is slidably connected to the lamination processing positioning plate 201. A limiting cylinder 301 is fixedly mounted inside the cylinder 3, and a lamination printing drive rod 4 is slidably connected to the limiting cylinder 301. A printing relief plate 403 is provided at the bottom of the lamination printing drive rod 4. An annular tube 307 is provided at the bottom of the cylinder 3, and multiple fan-shaped spray heads 308 are provided on the outer wall of the annular tube 307. A coating slurry pushing cylinder 302 is fixedly mounted on the inner wall of the bottom of the cylinder 3, and a liquid outlet pipe 306 is provided between the coating slurry pushing cylinder 302 and the annular tube 307.

[0022] In this embodiment, during use, the two ends of the nylon fabric are connected to the take-up roller and the unwind roller respectively, thereby realizing the take-up and unwinding operation of the nylon fabric. Simultaneously, silver paste is injected into the inner wall of the bottom of the cylinder 3. During the printing and silver plating operations, the cylinder 3 is first controlled to move downwards on the lamination positioning plate 201, so that the printing plate 403 first contacts the nylon fabric, thereby realizing the printing operation. Then, as the cylinder 3 continues to move, it will drive the printing plate 403 to move the lamination printing drive rod 4. When the lamination printing drive rod 4 moves, it will... The compression coating paste is pushed into the cylinder 302 to squeeze the silver paste material into the annular tube 307, and then sprayed out through the fan-shaped spray head 308 on the annular tube 307 to achieve the silver plating effect. During the silver plating operation, the printing plate 403 is kept in contact with the nylon fabric, so the fan-shaped spray head 308 can avoid spraying the silver paste material onto the printing area, thus ensuring the printing effect. After the printing and silver plating operations are completed, the cylinder 3 moves upward, so that the printing plate 403 separates from the nylon fabric.

[0023] In practical applications, the nylon fabric input end of this device can be connected to an unwinding assembly in the prior art. This unwinding assembly is used to smoothly and with constant tension transport the nylon fabric to be processed to the printing and silvering station of this device. The rear side of the drying area at the fabric output end of this device is connected to a winding assembly in the prior art, which is used to smoothly wind up the nylon fabric that has been printed, silvered, and dried. The selection, installation, and connection methods of the above-mentioned unwinding and winding assemblies are all conventional technical means in the field of textile fabric processing. Those skilled in the art can flexibly select and match them according to actual processing needs without creative labor. After the printing and silvering operations are completed, the winding assembly and the unwinding assembly are controlled to rotate a certain distance to perform silvering and printing operations on the next area of ​​the nylon fabric.

[0024] It should be noted that the silver paste used for silver plating in this application is a special sprayable silver paste for textile fabrics. Its formula and physical properties are specially designed to have good spray compatibility. It can be atomized and directionally sprayed through the spray head, and after spraying, it can be evenly adhered to the surface of the non-printed area of ​​the nylon fabric, while meeting the functional requirements of the silver layer and the flexibility requirements of the fabric.

[0025] The coating slurry pushing cylinder 302 is provided with multiple circumferentially distributed cylinders. Each of the multiple coating slurry pushing cylinders 302 is provided with a liquid extraction pipe 305 and a liquid outlet pipe 306. The end of the liquid extraction pipe 305 away from the coating slurry pushing cylinder 302 is connected to the bottom of the cylinder 3, and the end of the liquid outlet pipe 306 away from the coating slurry pushing cylinder 302 is connected to the annular pipe 307.

[0026] In this embodiment, when the lamination printing drive rod 4 moves upward, the silver paste material in the coating paste pushing cylinder 302 is discharged through the liquid outlet pipe 306, thereby entering the annular pipe 307 and then being sprayed through the fan-shaped spray head 308 to achieve a silver plating effect. After the cylinder 3 moves upward, the lamination printing drive rod 4 moves downward and resets under the action of gravity. In order to facilitate use, a spring can be set between the lamination printing drive rod 4 and the top inner wall of the cylinder 3 to increase the pressure between the lamination printing drive rod 4 and the cylinder 3, which facilitates the automatic reset operation of the lamination printing drive rod 4. When the lamination printing drive rod 4 resets, the coating paste pushing cylinder 302 will draw liquid into the cylinder 3 through the liquid extraction pipe 305 to realize the next silver plating operation, which is more convenient to use.

[0027] It should also be noted that the core material that the printing plate 403 in this application needs to dip into for printing is a textile-specific water-based high thixotropic printing paste. It can be combined with water-based pigments and trace amounts of functional additives according to the product's functional / decorative requirements. This type of paste is specifically designed for press-type letterpress printing and is compatible with the operation logic of transferring the printing after dipping into the plate. Before use, the printing material is first dipped into the printing plate 403 to achieve the printing operation. Each dip can achieve a long printing operation, which perfectly matches the core requirement of simultaneous printing and silver plating in this application. It ensures that the printed pattern is clear and formed, and can achieve physical avoidance of plating in non-printed areas. It is also highly compatible with silver paste and nylon fabric substrates, and can be dried and cured simultaneously with the silver layer.

[0028] Example 2: Refer to Figures 1-10A collaborative processing device for printing and silver plating of nylon fabric includes a support plate 1 and a lamination processing positioning plate 201 fixedly mounted on the support plate 1. A cylinder 3 is slidably connected to the lamination processing positioning plate 201. A limiting cylinder 301 is fixedly mounted inside the cylinder 3, and a lamination printing drive rod 4 is slidably connected to the limiting cylinder 301. A printing relief plate 403 is provided at the bottom of the lamination printing drive rod 4. An annular tube 307 is provided at the bottom of the cylinder 3, and a plurality of fan-shaped spray heads 308 are provided on the outer wall of the annular tube 307. The coating slurry pushing cylinder 302 is fixedly installed on the bottom inner wall of the cylinder 3. A liquid outlet pipe 306 is provided between the coating slurry pushing cylinder 302 and the annular pipe 307. The coating slurry pushing cylinder 302 is provided with multiple cylinders distributed circumferentially. Each of the multiple coating slurry pushing cylinders 302 is provided with a liquid extraction pipe 305 and a liquid outlet pipe 306. The end of the liquid extraction pipe 305 away from the coating slurry pushing cylinder 302 is connected to the bottom of the cylinder 3, and the end of the liquid outlet pipe 306 away from the coating slurry pushing cylinder 302 is connected to the annular pipe 307.

[0029] Furthermore, the top of the lamination printing drive rod 4 is provided with an L-shaped connecting plate 5, the bottom of the L-shaped connecting plate 5 is provided with an annular plate 501, the annular plate 501 is slidably disposed on the outer wall of the limiting cylinder 301, the top outer wall of the annular plate 501 is provided with multiple connecting rods 304, the top outer wall of the multiple connecting rods 304 is provided with piston plates 303, and the multiple piston plates 303 are respectively slidably disposed inside the multiple coating paste pushing cylinders 302.

[0030] A limiting plate 502 is provided on the top outer wall of the limiting cylinder 301, and a limiting groove 503 is provided on the limiting plate 502. The L-shaped connecting plate 5 is slidably disposed in the limiting groove 503.

[0031] A push block 401 is fixedly installed at the bottom of the lamination printing drive rod 4. A slider 402 is slidably installed on the push block 401. A printing plate 403 is installed at the bottom of the slider 402. A groove 404 is provided on the push block 401. The slider 402 is slidably installed in the groove 404. A spring sheet is provided between the slider 402 and the inner wall of the groove 404.

[0032] The outer wall of the push block 401 is provided with a groove 405, and a guide block 407 is slidably disposed in the groove 405. A cover plate 408 is connected to the guide block 407. The cover plate 408 is slidably connected to the outer wall of the printing plate 403 and the push block 401. An elastic element 406 is provided between the guide block 407 and the inner wall of the groove 405.

[0033] In this embodiment, during the printing and silver plating operations, the cylinder 3 is first moved downwards, causing the cover plate 408 at the bottom of the cylinder 3 to contact the nylon fabric. Then, under the continuous movement of the cylinder 3, the guide block 407 on the cover plate 408 slides within the groove 405, simultaneously compressing the elastic element 406. When the cover plate 408 reaches its limit position, the printing plate 403 contacts the nylon fabric, thus achieving the printing operation. Simultaneously, the printing plate 403 pushes the lamination printing drive rod 4 upwards, causing the L-shaped connecting plate 5 connected to the lamination printing drive rod 4 to move, which in turn moves the annular plate 501, causing multiple connecting rods 304 to move upwards, and causing multiple piston plates 303 to move upwards respectively. The coating paste is slidable inside the cylinder 302, squeezing the silver paste material inside the cylinder 302 and causing it to be discharged through the outlet pipe 306. Then, it enters the annular pipe 307 and is discharged through the fan-shaped spray head 308, achieving a silver plating effect. Under the action of the cover plate 408, the sprayed silver paste material can be prevented from interacting with the printing plate 403, improving the printing and silver plating effect. After the cylinder 3 moves upward and resets, it will drive the lamination printing drive rod 4 to automatically reset. At the same time, the piston plate 303 moves downward inside the coating paste pushing cylinder 302, and the silver paste material at the bottom of the cylinder 3 is extracted through the extraction pipe 305, thus facilitating the next silver plating operation. The elastic element 406 can be a spring or a spring sheet, etc.

[0034] It should also be noted that both the extraction pipe 305 and the outlet pipe 306 are equipped with one-way valves, which ensure that the extraction pipe 305 only performs the function of extraction, preventing the silver paste material from being discharged from the extraction pipe 305. Similarly, the outlet pipe 306 only performs the function of discharging the silver paste material, preventing the silver paste material in the outlet pipe 306 from flowing back when the coating paste pushing cylinder 302 extracts the silver paste material, thus facilitating the spraying effect and making it more convenient to use.

[0035] When the printing plate 403 moves, it will drive the slider 402 to slide in the groove 404 in the push block 401. At the same time, with the spring sheet inside the groove 404, the printing plate 403 can generate a certain buffering effect, improving the performance of the printing plate 403. In addition, the L-shaped connecting plate 5 can slide in the limiting groove 503 on the limiting plate 502, which can improve the connection effect between the L-shaped connecting plate 5 and the annular plate 501, making the movement more stable.

[0036] Example 3: Refer to Figures 1-7A nylon fabric printing and silver plating collaborative processing device includes a support plate 1 and a lamination processing positioning plate 201 fixedly mounted on the support plate 1. A cylinder 3 is slidably connected to the lamination processing positioning plate 201. A limiting cylinder 301 is fixedly mounted inside the cylinder 3, and a lamination printing drive rod 4 is slidably connected to the limiting cylinder 301. A printing relief plate 403 is provided at the bottom of the lamination printing drive rod 4. An annular tube 307 is provided at the bottom of the cylinder 3, and multiple fan-shaped spray heads 308 are provided on the outer wall of the annular tube 307. A coating slurry pushing cylinder 302 is fixedly mounted on the inner wall of the bottom of the cylinder 3, and a liquid outlet pipe 306 is provided between the coating slurry pushing cylinder 302 and the annular tube 307.

[0037] Furthermore, an installation plate 2 is fixedly installed on the outer wall of the support plate 1, and the lamination processing positioning plate 201 is fixedly connected to the installation plate 2. A cylinder 202 is provided on the top outer wall of the lamination processing positioning plate 201, and the cylinder 3 is connected to the output end of the cylinder 202.

[0038] Multiple circumferentially distributed guide rods 203 are provided on the top outer wall of the cylinder 3. The multiple guide rods 203 are slidably connected to the lamination processing positioning plate 201. A feed pipe 309 is provided on the outer wall of the cylinder 3.

[0039] In this embodiment, by activating the cylinder 202, the cylinder 3 at its output end can be moved. At the same time, the guide rod 203 can slide on the lamination positioning plate 201, which can improve the stability of the movement of the cylinder 3. The mounting plate 2 can better connect the lamination positioning plate 201 and the support plate 1, making installation convenient. The feed pipe 309 can inject silver paste material into the cylinder 3. The injected silver paste material will be placed between the bottom inner wall of the cylinder 3 and the bottom of the annular plate 501.

[0040] A drying box 6 is fixedly connected to the support plate 1. A drying cylinder 601 is provided inside the drying box 6. The fiber fabric passes through the drying box 6. A horizontal plate 101 is fixedly installed on the support plate 1. The horizontal plate 101 is located below the printing relief plate 403.

[0041] In this invention, after printing and silver plating, the nylon fabric passes through the drying box 6 and is dried by the drying cylinder 601, which facilitates the curing of the silver plating and printing operations and prevents scratches during subsequent winding. The horizontal plate 101 is provided to support the nylon fabric and makes it easier to carry out subsequent printing and silver plating operations.

[0042] Example 4: A method for co-processing printing and silver plating on nylon fabric, comprising the following steps: Step 1: Connect both ends of the nylon fabric to the external take-up roller and unwind roller, respectively. Step 2: Inject silver paste material into the inner wall of the bottom of the cylinder 3. Step 3: First, control the cylinder 3 to move downward on the lamination positioning plate 201, so that the printing plate 403 first contacts the nylon fabric, thereby realizing the printing operation. Step 4: The cylinder 3 continues to move downward, thereby driving the lamination printing drive rod 4 to move and squeeze the coating paste to push the silver paste material into the cylinder 302. Step 5: Squeeze it into the interior of the annular tube 307, and then spray it out through the fan-shaped spray head 308 on the annular tube 307, thereby achieving the silver plating effect.
